[ Maxim on SAR ADCs ] <— binary search?
Good news is that we finally realized what we could use our c5515’s SAR ADC for…directly grabbing the six analog inputs on the Arduino! There seems to be a perfect one-to-one mapping here, because here’s what the Arduino has:
The Atmega controllers used for the Arduino contain an onboard 6 channel analog-to-digital (A/D) converter. The converter has 10 bit resolution, returning integers from 0 to 1023.
Which is exactly what our SAR ADC can do! Perhaps with a better SNR?
